Roth conversion timing can trap savers with unexpected penalties

According to 26 U.S.C. § 408A(d)(3)(F), a portion of a Roth distribution might originate from a conversion and be considered an early distribution, potentially incurring the 10% tax. This is further clarified in 26 CFR 1.408A-6, A-5(b). The five-year period begins on the first day of the tax year of the conversion and concludes five years later. Crucially, this period is “separately determined for each conversion contribution,” as outlined in 26 CFR 1.408A-6, A-5(c).

The tax applies solely to the portion of the conversion that was included as income. While the standard tax doesn’t apply at the time of conversion (26 CFR 1.408A-4, A-7(b)), it can be levied later. Publication 590-B (2025) states that the 10% penalty is assessed “in the year of the distribution,” even if the conversion was previously included in income.

Earnings, however, become tax-free only upon a qualified distribution – meeting conditions such as reaching age 59½, experiencing death or disability, and surpassing the five-year period from the first Roth contribution (26 U.S.C. § 408A(d)(2)). This overall five-year period begins with the initial regular contribution or the first conversion, according to 26 CFR 1.408A-6, A-2.

When withdrawals are made, regular contributions are taken first, followed by conversion and rollover contributions (on a first-in, first-out basis, with the taxable portion of conversions prioritized), and finally, earnings. All distributions from Roth IRAs are combined, preventing strategies to avoid this order (26 CFR 1.408A-6, A-9(a)).

Consider Mark, who turned 52 in 2022. He made $20,000 in regular contributions since 2018 and has converted $30,000 in 2022, $30,000 in 2024, and $30,000 in 2026. In 2027, at age 57, he withdrew $70,000. The first $20,000 came from regular contributions, tax and penalty-free. The next $30,000 came from the 2022 conversion, which had already cleared its five-year penalty clock. The remaining $20,000, from the 2024 conversion, triggered the 10% penalty, totaling $2,000.

Several exceptions can eliminate the 10% penalty, including reaching age 59½, disability, or experiencing a qualified disaster. Once an individual reaches 59½, the conversion clocks no longer apply for penalty purposes.

To navigate Roth conversions effectively, individuals should assess their future cash needs, meticulously track conversion details (year and taxable amount), and consider the indirect effects on Social Security and Medicare premiums. Roth conversions are not suitable for those who anticipate needing the funds within five years of the conversion, without a qualifying exception, as the penalty can negate the conversion’s benefits. Those who can avoid touching converted funds until the five-year period expires or until age 59½ can avoid this risk.
